One tip from EMS when you're dealing with odors that nearly drive you out of the house, and you don't want to use a respirator: a dab of vicks vapor rub under your dust mask.

If nobody will be inside the house, vapor strips for the flies and mosquitos.

Its a vapor barrier, but also insulates and reflects heat as well.

And due to the vapor barrier, (a huge plastic sheet) all the little (and not so little ) poopies stayed nice moist and fresh!

.- Blown insulation in attic- New deck- Crawlspace remediation and encapsulation- french drain, sump pump, blown insulation, vapor barrier, dehumidifier.- Landscaping front and back beds.

There does not appear to be a vapor barrier.

Least of all me, there is absolutely nothing a CG will advise me on from the size of a ring nail on shingles to the vapor liner below grade of the foundation, nothing, if I need an advisor I'll ask an engineer.And, contractors will do well to hook up with good investors.

Hi Deborah BurianTake a look on a website called buildingscience dot comI'll try to link to an article...no affiliation, just a good reference site:http://www.buildingscience.com/documents/digests/bsd-106-understanding-vapor-barriersI'd say if that wall doesn't have it, none of them do.

Hopefully the price included a vapor barrier and gravel?

As you don't have listed where you are - and you did not state what kind of foundation it is - we have no idea if it is a slab or a basement foundation, no idea how old the foundation is, what construction materials, what construction quality, completely in-ground versus walk-out (if not a slab), what was the cause of the explosion, how bad was the explosion (did it vaporize the house or just start a fire that necessitated razing the house... and on, and on....Even if the county approves re-using the existing foundation, I would not rely on the county inspector - after all, they just inspect things to code - the DO NOT inspect things as would a structural engineer.
